Neptune

--Neptune has 14 moons, the largest of which is Triton. Triton is thought to be the coldest planet in the solar system

Neptune's atmosphere is about 80% hydrogen and 19% helium, with trace amounts of methane. The methane gives Neptune its deep blue colour. Neptune is very similar to Uranus in terms of its internal structure. However, Neptune has more dynamic weather than Uranus, due to its internal heating.
